Bacteriological Status Of Meat During Various Stages Of Processing In AFD Packing Plant

Studies on eight carcasses(sheep/goat) for microbial status of meat at different stages of processing viz dressed carcass before after chilling, after boning, cocking, cooking, cooling, slicing, deep freezing, freeze drying, and packing have been carried out. No difference in microbial status has been observed in sheep and goat carcass. The lower (front body) portion of carcass has higher microbial load than the upper portion (hind body). No significant increase in total colony counts was observed on keeping the carcass for 24 hours at 5 degree centigrade. The highest microbial load has been observed on boned meat. The total colony counts (TCC) gets reduced during the process of deep freezing and freeze drying. The precooked, freeze dried meat has TCC up to 266

The stability of adaptive synchronization of chaotic systems

In past works, various schemes for adaptive synchronization of chaotic systems have been proposed. The stability of such schemes is central to their utilization. As an example addressing this issue, we consider a recently proposed adaptive scheme for maintaining the synchronized state of identical coupled chaotic systems in the presence of a priori unknown slow temporal drift in the couplings. For this illustrative example, we develop an extension of the master stability function technique to study synchronization stability with adaptive coupling. Using this formulation, we examine local stability of synchronization for typical chaotic orbits and for unstable periodic orbits within the synchronized chaotic attractor (bubbling). Numerical experiments illustrating the results are presented. We observe that the stable range of synchronism can be sensitively dependent on the adaption parameters, and we discuss the strong implication of bubbling for practically achievable adaptive synchronization.Comment: 21 pages, 6 figure

Efficacy of Grout Curtain at Ramganga Dam

The analysis of foundation piezometer records at main dam and saddle dam of Ramganga Project, has indicated that the single row grout curtain at main dam, is ineffective so far as the hydrostatic pressure reduction in foundation is concerned, whereas under similar conditions, upstream impervious blanket at saddle dam, is more effective in pressure reduction. Experimental test results by electrical analogy technique using graphite paper, has indicated that in case of Ramganga main dam, the total net pressure reduction for fully effective grout curtain would have been only 25%. The design curve for efficiency versus different openings in grout curtain is also given
